Given the altitude and airspeed at the point of disappearance the plane, or parts of it, will likely be quite some distance south east of the last know location, which could be in shallower parts of the Med.

Discarding the usual creative but pointless theories, all we know with any degree of certainty is that the plane disappeared suddenly at cruising altitude (or thereabouts) having just entered Egyptian airspace. The rapidity of the event suggests some kind of very sudden 'mechanical' failure - cause unknown. Realistically there are only two broad possibilities; explosive device or a sudden mechanical/structural/engine-type failure.

For some reason I can't help feeling that there is some significance in whatever happened did so just as the flight entered Egyptian airspace.

  [snip] A commercial pilot with a major European airline told The Telegraph that other parts of the data log suggested that windows in the right side of the cockpit were blown out by an explosion inside the aircraft... The data was taken from the plane's Acars system, which sends short transmissions from the aircraft to receivers on the ground. Until investigators find the aircraft's black boxes, which are still missing in the Mediterannean, the Acars offers the best sens on what was happening aboard... That does not mean the explosion came from the cockpit but indicates the right side of the plane was more badly damaged than the left. The pilot suggested the smoke detectors may have been triggered not fire but by fog which filled the cabin as it lost air pressure in the moments after the explosion... [/snip]

According to the Guardian
http://www.pprune.org/rumours-news/579183-egyptair-804-disappears-radar-paris-cairo-2.html

‘EgyptAir says that the plane’s emergency devices (possibly an emergency locator transmitter or beacon) sent a distress signal that was received at 4.26am, some two hours after the previously stated last radar contact.’

You turn 90 degrees to deconflict with other aircraft. It gets you out of the established airway, so if you are radio out you don’t have to worry about aircraft coming the other way, or traveling near you.

What I remember from a LONG time ago about no radio distress signal is flying a 2 minute leg after the 90* turn, then a series of 3 X 120* turns at 2 minute intervals. After performing 2 triangles, resume regular flight path for 5 minutes, then repeat the distress signal.

In a jet, the interval is reduced to one minute per leg.

This information is NOT gospel, as I said it’s from memory of pre-flight school 40+ years ago.
